Self Hosted NFT Maker ArcBlock Mainnet Option

Yoo! So I want to use the NFT maker to create a collection of Passports that form a DAO for Todai. While testing out the Blocklet to ensure everything is working smoothly, I noticed that there was no option to create a Collection directly on the "ArcBlock Mainnet." The default options were only testnets, aside from the Base option.

I checked the "Configuration" area, and could not find anything to help either.

Is the option to do so currently not available on self-hosted Blocklets?

If it is, can you help me to activate that feature, or point out where I need to go to do so?

Thanks for your help in advance!
